GUN -LOCK.

Specification of Letters Patent.

Patented Oct. 22, 190?.

Application filed June 7,1907. Serial No. 377,811.

To all whom it may concern:

Be it known that I, WILLIA M J. MoLLoY, a citizen of the United States, residing at Chicago, in the county ol Cook and State of Illinois, have invented certain new and useful Improvements in Gun-Locks, ol' which the following is a specilication.

This invention relates to gun locks for double-barrel guns, and has tor its object to provide a lock which can be changed l'rom one barrel to the other. to tire either.

A further object is to provide an improved i'orin of lock, with respect to the hammer operating devices.

The invention is illustrated in the accompanying drawings, in which Figure l is a vertical section ol' the lock. Fig. 2 is a side elevation. Fig. 3 is a planview ol the lock, the stock being broken away to show the same.

Referring specifically to the drawings, 1 indicates the base or frame of the lock, and it is arranged to swing laterally upon the bottom 2 ol the recess formed in the stock to receive it. The liame is pivoted at the rear end, at the middle line ol' the stock, by a screw 9, and the front wall of the rcccs is made in the form of an arc of a circle to allow the lateral swing. Normally, the lock stands in position to lire the lci't barrel. being so held by a spring connected between the l'rame ot the lock and the face plate at the side 01' the recess. and also held by a latch 15, with a spring thereundtn', which is set in the floor of the recess and which engages in a notch in the under side oi the lock 'l'ranie l. The head ol' the latch is rounded so that it will yield when special effort is applied to the lock. The lock may he swung to the right barrel by means of a push pin 24 which is exposed through the side plate and may be pressed by the thumb to force the lock o'v er to the right side while that barrel is being tired, after which the spring 25 will swing the same back to the left barrel. The lock itsell is of the kind in which the han'nner is not exposed, and is sell-c .)cking.

The hammer is indicated at 3, pivoted at 4. and it carries a stirrup 5pivoted at (i and connected to the main spring '7 which is fastened to the rear block of the case I by means of the screw 8. The trigger ll is l'ulcrumcd at 225, and carries a thrust bar or li'l'ter 10 which engages a too 3 at the base oi the hammer.

The litter spring is shown at 12, secured to the under side of the litter and bearing upon an inclined tension plate 13 which is pivoted at its rear end in the lock frame and at its front end is adjustable by means of a pointed screw 14 which can be advanced or retracted to vary the inclination of the plate 13 and consequently to vary the tension upon the spring 12 and the litter in the act of firing.

I i i i i The trigger spring is indicated at 27, set in the lock lrame behind the plunger 26 which bears against the heel of the trigger, and returns the same to normal position after each operation.

17 is a back stop or idler behind the head of the trigger.

Ea ch barrel has aliring pin 18, in proper position to be struck by the hammer, and the pins are retracted by their springs 19.

20 is a sai'ety plunger set in front of the hammer, in the front end of the lock frame, with the spring 21 behind the saine. This safety plunger serves to prevent l v 1 accidental drop or contact or the hammer against the firing pin, which might result in an accident.

In the operation of the lock, pull on the trigger advanccs the litter and cocks the hammer, and continued movement causes the lower extremity or extension of the stirrup 5 to bear down on the litter and disengage same from the toe 3, allowing the main spring to act to throw the hammer against the firing pin.

The manner in which the lock may be swung from one barrel to the other has been explained above. The arrangement or invention saves the cost oi one lock, by enabling the single lock to be used 011 each barrel.

Various modifications or different arrangements may be made without departing from the idea or scope of the invention indicated in the following claims.

I claim:

1. The combination with a gun having several barrels, of a lock movable from one barrel to the other.

2. The combination with a double-barreled gun, of a lock pivoted at its rear end, behind the barrels, and means to swing the same from one barrel to the other.

i The combination with a double-barrelcd gun, and a tiring pin for each barrel, of a lock movable behind the barrels. from one to the other, to register its hammer with either tiring pin.

-l. The combination with a double-barreled gun, of a lock movable from one to the other, a spring for moving the lock to one barrel, and a push button for moving the same to the other.

In a gun lock. the combination of a hammer having a toe. n stirrup pivoted thereto and connected to the main spring and having an extension projecting downward behind the toe. and a spring-supported lifter connected to the trigger and projecting under said extension and against the toe and arranged to be pressed down by said extension and disengaged from the toe when the trigger is pulled.

In testimony whereof I allix my signature, in presence of two witnesses.

WILLIAM J. MOLLOY.
